Code:
[yuv4mpegpipe @ 000002b3aada8c00] Header too large.

points to some problem with Vapoursynth.

The Vapoursynth script:

# set output frame rate to 62.5fps (progressive)

clip = core.std.AssumeFPS(clip=clip, fpsnum=60000, fpsden=960)

# output

clip.set_output()

seems fine.

Don't see anything strange happening with the resolution. (RIFE requires mod32, which is why Hybrid pads the source and removes the padded borders)

Using latest dev with:

# adjusting color space from YUV420P8 to RGBS for vsRIFEmlrt

clip = core.resize.Bicubic(clip=clip, format=vs.RGBS, matrix_in_s="470bg", range_s="limited")

# adjusting frame count&rate with RIFE (mlrt)

clip = vsmlrt.RIFE(clip, multi=Fraction(2.4), model=424, backend=Backend.ORT_CPU(fp16=False), ensemble=True) # new fps: 60

# adjusting output color from: RGBS to YUV420P10 for NVEncModel

clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, matrix_s="470bg", range_s="limited", dither_type="error_diffusion")

# set output frame rate to 60fps (progressive)

clip = core.std.AssumeFPS(clip=clip, fpsnum=60, fpsden=1)

# output

clip.set_output()

causes no problem and uses (aside from the Fraction) the same RIFE call:

Code:
clip = vsmlrt.RIFE(clip, multi=Fraction(2.4), model=424, backend=Backend.ORT_CPU(fp16=False), ensemble=True) # new fps: 60

=> What does the Vapoursynth Preview say?

Audio - OK
Video finished with exit code -22
Crashed with exit staus 0

Perhaps it's because the PC can't handle RIFE?

Quote:Perhaps it's because the PC can't handle RIFE?

To know that, I asked you what the Vapoursynth Preview says. Does it properly show the preview or does it show an error message?
Also using another backend might work. Not all backends work on all machines.

Cu Selur

It properly shows a preview.

I just tried again, but same error messages and crash.

This is using an old HP Z420 Workstation, I guess the spec is not good enough?

If the Vapoursynth Preview works fine with your settings, then my guess would be that you are running out of RAM or VRAM or something is interfering with the encoding.

"HP Z420 Workstation" that doesn't really say much.
This you try different backends, like I suggested?

OK, looks like I need a better PC, after a re-boot I now see this:

Failed to evaluate the script:
Python exception: RIFE: invalid GPU device

vapoursynth.Error: RIFE: invalid GPU device

"gpu_id=1"<- this will select the second gpu in your system, by default gpu_id=0,...

Is this "force gpu" = 1? I think that was the setting I tried.

Yes, with force gpu you force a specific gpu,...

The only one that works is SVP - MVTools looks poor, FrameRateConverter also not so good, and RIFE crashes. I will need to look for a better PC, but I have no idea what sort of specs I would need to properly run RIFE?
